MySQLNonTransientConnectionException when getting ssl connnection to mysql from tomcat application - mysql

Question

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException been raised when attempting to make an SSL connection to MySQL from a tomcat-based application.
I have tried the same code in a Java class in the main method without tomcat (like a Java project in eclipse). This program works fine, i.e. I am able to get an SSL connection to the database.
Error code:
DriverManager.getConnection("jdbc:mysql://localhost:3306/ibisdb74?verifyServerCertificate=true&useSSL=true&requireSSL=true&clientCertificateKeyStoreUrl=file:/home/directoryA/mysql_certs_latest4/keystore&clientCertificateKeyStorePassword=mypass&trustCertificateKeyStoreUrl=file:/home/directoryA/mysql_certs_latest4/truststore&trustCertificateKeyStorePassword=mypass","root","root");
Exception trace:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Cannot open file:/home/gom7kor/mysql_certs_latest4/truststore [keystore password was incorrect]

I looked for a successful encrypted connection without an exception, even in the tomcat based application.
PS: I am getting this exception with a tomcat based application, but not in non-tomcat applications. And I am using jdk 11 and tomcat 9.
